I ended up having five different Xbox 360's last gen, and only one remains working. The first, which I bought Christmas 2005, RROD'd in about five months, before MS instituted the extended warranty. After that year ended, I eventually haggled them into replacing mine, and that one died pretty quickly too. I eventually just bought one of the Slim models, and it's still working fine about five years later.
I did have one PS3 die on me, as well. My launch system didn't make it, which wasn't too big a deal as I had already had bought a separate Slim.
My launch PS4 doesn't work right now, but it wasn't because of faulty manufacturing. A lightning bolt struck my yard while I was playing a game (it wasn't even storming) and fried not only my ps4, but my tv as well. The PS4's insides are still okay, but the HDMI input doesn't work. I'm probably going to get it fixed after I pay off the Pro.
Note: Despite my awful luck with the last couple of generations, I still have an SNES, Genesis, PS2, N64, Gamecube etc. that all still work perfectly fine.
